Android API calling with Retrofit method

 How to call API using Retrofit method , here we are looking  how to parse web API using Retrofit and with Header.

APIInterface apiInterface = RetrofitService.createService(ApiInterface.class, "BASE_URL", false);

the "false" is your Header boolean , if your web api having Header like "Bearer" token so the boolean is "true".

//Retrofit service method for all api calling

public static <S> S createService(Class<S> serviceClass, String serverURL, boolean withHeader) {

Gson gson = new GsonBuilder().setLenient().create();

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();

logging.setLevel(HttpLoggingInterceptor.Level.BODY);

httpClient = new OkHttpClient.Builder();

httpClient.addInterceptor(logging);

httpClient.connectTimeout(60, TimeUnit.SECONDS );

httpClient.readTimeout(60, TimeUnit.SECONDS );

// httpClient.addNetworkInterceptor(new AddHeaderInterceptor());

if (withHeader) {

httpClient.addInterceptor(new Interceptor() {

@Override

public Response intercept(Chain chain) throws IOException {

final Request request = chain.request().newBuilder()

//.addHeader("Accept", "application/json")

//.addHeader("Authorization","Bearer "+ Activity_Login.token)

//A1 update

.addHeader("X-Requested-With", "XMLHttpRequest")

.addHeader("Authorization", "Bearer "+"your token")

.build();

//SharedHelper.getKey(mContext, Str_RemeberLoginKey)

return chain.proceed(request);

}

}

);

}

builder = new Retrofit.Builder()

.baseUrl(serverURL)

.addConverterFactory(GsonConverterFactory.create(gson))

.addConverterFactory(ScalarsConverterFactory.create());

Retrofit retrofit = builder.client(httpClient.build()).build();

return retrofit.create(serviceClass);

}

Now , above is the method for api parsing .

Make your pojo class using api response and put it in your code and i here give you a code for api parsing using Retrofit method.

private void callRegister() {
 APIInterface  reg_api = RetrofitService.createService(ApiInterface.class, "BASE_URL", true);

    //str_fname,str_lname,str_phone
    RegisterBody regmodel = new RegisterBody();

    regmodel.setFirst_name(str_fname);
    regmodel.setLast_name(str_lname);
    regmodel.setCountry_code("+91");
    regmodel.setMobile(str_phone);
    regmodel.setPassword(str_password);

    Call<RegisterModel> callAdvisoryApi = reg_api.getRegister(regmodel);

    callAdvisoryApi.enqueue(new Callback<RegisterModel>() {
        @Override
        public void onResponse(Call<RegisterModel> call, Response<RegisterModel> response) {


            RegisterModel objRegisterModel = response.body();

            if (response.code() == 200) {

                

                Toast.makeText(mContext,"Register Successfully..",Toast.LENGTH_LONG).show();

                Intent myintent = new Intent(mContext, MainActivity.class);
                startActivity(myintent);

            } else {
           
                Utilities.displayMessage(mContext, "Could not signup..Please try again");
            }
        }

        @Override
        public void onFailure(Call<RegisterModel> call, Throwable t) {
            Toast.makeText(mContext, "Failed to load data" + t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
}

public interface ApiInterface {

    @POST("/api/user/signup")
    Call<RegisterModel> getRegister(@Body RegisterBody regmodelobj);

    @POST("/api/user/login")
    Call<LoginModel> postLogin(@Body LoginParameters params);
}
